Abstract
Using approximately 1.3 fb-1 of data collected by the D0 detector between 2002 and 2006, we measure the lifetime of the Bc± meson in the Bc±→J/ψµ±+X final state. A simultaneous unbinned likelihood fit to the J/ψ+µ invariant mass and lifetime distributions yields a signal of 881±80(stat) candidates and a lifetime measurement of Τ(Bc±)=0.448-0.036+0.038(stat)±0.032(syst) ps.
